Oiling The Cam Synchronizer?

Hey guys, I just bought a 99 Ranger 3.0L 2WD with 4900 miles on it. Yeah, 4900 miles and its awesome lol. Anyways I bought it to run around in hoping that it gets a little better mileage the my 04 4.0L 4WD. The truck only had the oil changed once on it so the first thing I did was change oil on it. (I used 5w30 Mobil 1 syn.). I have been reading up about this cam syncro problem and I was wondering if maybe any of you had tried putting a few drops of oil in it? I was reading over on RPS and a guy did that with every oil change. Not sure if it would help or not but I wanted to see what you thought. I am getting a little noise under the hood but I am thinking it is the belt or idler pulley/tensioner. I wouldnt think that the Cam synchro could be doing it so soon but I guess you never know. Let me know what you think. Also if anybody else has anything you feel I should know about the 3.0 let me know as it is my first one!

Go with 5w20 oil. The cam sync is splash lubricated through a very small hole.It won't hurt to try and add a teaspoon of oil in the top of it.Just keep it off the sensor.

I once had a little noise from mine, so I pulled the sensor off and poured a little on it. Instantly made the noise go away and never heard anything since

Hmm, I think I will try that. I know Ford decided to change the oil reccomendation on this engine to 5W20 but the sticker under the hood says to use 5W30. I used 5W30. How many of you on here run the thinner oil? I'm not sure what to put in next time.

I switched my truck to Motorcraft 5w-20 synthetic blend at 145k miles, been running it for 20k now. Great oil, engine is noticeably quieter. I plan on running this oil for as long as I own the truck.

I thought Ford started 5w20 in 2002? If your cap says 5w30 I would not use 5w20.

I doubt its that important, how many major changes did they make to the 3.0 between then and now? I think they switched weights for fuel economy.

I've heard about the small hole used for oil to splash onto the cam synchro...has anyone tried drilling out the hole a little bit to avoid plugging (ultimately leading to failure)?

Not much, make the hole 1/16'' oversized...maybe itll stop the plugging up so easily...just a thought.

I have my old one here and was looking at it.
The pin in the gear would have to be pressed out and the shaft removed , to clean out the filings, but it may be do-able.

That's where a shaped block of wood, a properly sized nail or bolt, and a HF (45 bucks, 38 or so with 20% off) 1 ton arbor press equipped with a cheater pipe comes into play. Then a good gear puller and a flat piece of metal with a relief cut to clear the shaft that the gear is pressed onto...

The cheapo arbor press has made several things much easier to do. Well worth the money.
